Answer:
Step-by-step explanation:
since the foci is (±5,0), the standard form of the hyperbola would be
directics = ±a^2/c
±2 = ±a^2/5
a^2 = 10
a^2+b^2=c^2
b^2 = c^2-a^2 =5^2-10 = 15
Answer:
Step-by-step explanation:
given are two vectors
a) A+B = sum of twovectors = simply adding corrsponding compnents
=
Magnitude of the above vector =
Direction is making an angle of arc tan (-3) with x axis
b) A-B = Difference
=
Magnitude of difference vector =
Direction is making an angle of arctan (1/2) with positive x axis.
(angle = arctan (jcomponent/icomponent)
Answer:
42.25cm^2
Step-by-step explanation:
8+5+8+5 = 26
26/4 = 6.5
